App only requires Touch/Face ID for the initial opening

[spuk-]

Steps To Reproduce

1. Go to the app settings tab
2. Enable "Unlock with Touch ID"
3. Press the home button to exit Authenticator
4. Tap on the Authenticator app to enter it again without requiring Touch ID

Expected Result

The app should require Touch ID to be opened.

Actual Result

The app is opened without requiring Touch ID.

The app only requires Touch ID when the app is reopened after being closed (i.e. Double press the home button for the apps list and push it off the screen for closing it).

I'd like to add that the same behavior is seen with Face ID.

I just submitted this feature request to support. I'd like to further add this request:

1. Touch/Face ID is required to view a raw TOTP key.
2. Touch/Face ID is required to export data

This further limits attackers from somehow getting access to a user's TOTP keys discretely if the user were to make the mistake of leaving the Authenticator app open and unlocked. An attacker couldn't sweep a user's TOPT data discretely with the intention to brute-force their accounts later on. The worst an attack could do in that event is attempt to brute-force their individual accounts in the moment they have access to opened app.
